This paper aims to investigate the use of expanded perlite in mortar, for further application of shotcrete to thermal insulation of underground mines. Mixes were designed according to the typical proportions of underground shotcrete, with the sand volumetrically substituted by expanded perlite. Tests of samples were conducted at four ages. Transient plane source technique was utilised to measure ...

Accessing critical resources such as geothermal energy and natural gas requires drilling — an expensive, energy-intensive, messy process with today's technology. An MIT team has been looking into a more elegant approach. Instead of grinding rock to bits, they would use a continuous beam of energy to vaporize it and then blow out the tiny particles that form with a high-pressure stream of ...

Imtech was commissioned to undertake a Station Modernisation and Enhancement Project at Morden Station which comprised of the provision of new electrical and mechanical services as well as modification to the existing. As Morden is the last station on the Southern end of the Northern Line, work was restricted by very short engineering hours (typically 2 1/2 hours work per shift). All switchrooms ...

The prediction of pipe failures in water distribution systems is an essential planning tool for water companies. Previous methods focus on the prediction of either future failure numbers or aspects of pipe condition. However, most of these only predict at the level of large pipe groups (of similar characteristics) and often cannot provide uncertainty bounds. Here, a new statistical method is ...

Former fueling operations at Scott Air Force Base resulted in soil contamination containing high levels of benzene, ethylbenzene, methyl tertiary-butyl ether (MTBE), and naphthalene. Underground storage tank removal and source area excavation were planned to treat the unsaturated soil. However, subsurface investigations revealed piping, fiber-optic communication lines and other utilities present ...

The groundwater used as drinking water often contains unacceptable amounts of iron and manganese compounds and ammonium ions. These substances are efficiently removed using conventional technologies (aeration and filtration through granular media filters). However, the efficiency is drastically reduced for water containing considerable amounts of organic matter, which usually enters the water ...

At the North River Mine in Berry, AL, two waste streams are created from the processing plant, coarse rock and fine rock particles. Coming from the processing plant, the fine rock particles are suspended in water forming a slurry. This slurry is normally disposed of via surface impoundments or injected into abandoned underground mine workings. The volume of this waste stream is very significant ...

Electrical Monorails have several advantages over trackless haulage in underground mining, such as ability to negotiate steep vertical and tight horizontal curves, small operating room and less diesel fumes. It has been demonstrated that loading time is the main drawback to high advance rates in monorail application whereby a loader is used to load rocks into monorail containers. A pneumatic ...

Summary A former fueling facility in Port Coquitlam, BC contained four underground storage tanks (USTs) and accompanying dispensers. The USTs were removed in 1990 after volatile petroleum hydrocarbon (VPH) concentrations were foundabove regulatory limits. Source well BH206 had significant VPH and naphthalene concentrations reaching 13,000 ug/L and 240 ug/L, respectively. In addition, ...
